Permits & your utility in Mountain House

In Mountain House, electric service is Modesto Irrigation District (MID), and building permits are issued by San Joaquin County. We pull the permit on every solar & battery, coordinate the service and meter to MID's MID Electric Service Guides — Residential Service Guide (of 8 guides), and pass inspection, so it's safe, legal, and protects your home's value.

Mountain House note: PG&E provides only GAS here; electric = MID since 2001. Not obvious for a San Joaquin new-growth area.

solar & battery in Mountain House: FAQ

Do I need a panel upgrade for a battery in Mountain House?+

Often yes — battery and solar interconnections must meet NEC 705.12 (the 120% rule). We check your busbar rating and, if needed, upgrade to a solar-ready 200A panel so it's done once, correctly.

Can you add backup without full solar?+

Yes. A Tesla Powerwall or battery can back up your essential circuits with or without solar. We size it around your must-run loads — fridge, Wi-Fi, medical, well pump.
